| Abstract: | A static load test of 30m boxed was made in a certain expressway engineering.In the test,the working performance,deflection and stress,of the precast girderwere both tested at different load effect levels.Then, com?paring and studying the observation results and theoretical values,combined with the design specification of high?way reinforced concrete and prestressed concrete bridges and culverts, judging the safety and stability of the structure. |
